Federal Medicaid spending falls
The requirement is the single largest saving in the 2025 law's Medicaid provisions, scored at 326 billion dollars of spending over ten years, less 8.65 billion of tax revenue that goes with it. Almost all of it comes from people leaving the programme rather than from anyone finding work. Part of it does not stay saved, because people without coverage still turn up in emergency rooms.

Value
The stream is federal money, priced at the middle of the scale like every other dollar on this site. Public money is not treated as worth more or less than private money; the difference between what a dollar is worth to a government and what it is worth to a household at the other end of the transfer is counted in the Impact. Nothing about what Medicaid buys enters here, because that is counted on the other side of the ledger. Nor does the deficit make the saving worth more: reducing borrowing shifts who pays and when, and that shift is inside the dollar figure already. The value is the middle of the scale, the level this site uses for public money whatever it is spent on.
Impact
The budget office scores the work requirement at 326 billion dollars of reduced federal Medicaid spending over ten years, the largest single item among the law's Medicaid provisions; the same estimate carries 8.65 billion dollars of lost federal revenue over the decade, because some of those who leave move into employer coverage that is exempt from tax [1]. Net, that is about 317 billion dollars, 31.7 billion a year. The requirement begins in January 2027 and states phase it in over the following year, so about 85 percent of the annual rate is reached across the four years counted here: about 27 billion dollars. Not all of that stays saved. People who lose coverage do not stop getting ill; they arrive at emergency departments, where the bill is written off. When Tennessee removed adults from Medicaid in 2005, each person who became uninsured added close to 900 dollars a year of unpaid hospital care, two thirds of it absorbed by the hospitals and a third passed on to other payers [13]. For this law, hospitals in expansion states are projected to write off 7.0 to 8.0 billion dollars more in 2027 for 5.1 to 5.8 million newly uninsured, about 1,400 dollars a person [11]. For 4.0 million people that is about 5.4 billion dollars, a fifth of the federal saving, in a range from 5 to 35 percent; it is subtracted because the care goes on and somebody else pays for it, leaving about 21.6 billion dollars a year. The federal dollar carries the standard weight of one. The Impact is the largest in this debate, and it is large because the saving comes from removing coverage rather than from anyone changing their behaviour.

| Federal Medicaid spending the requirement removes, net of the revenue lost with it the budget office's estimate for the enacted law; converted at 1.16 dollars to the euro [1] | 326 billion dollars less 8.65 billion of revenue over ten years, about 31.7 billion a year | 27.4 billion euro-equivalent | |
| × | Share reached across the first four years Setting, range 70 to 100 percent: the requirement starts in January 2027 and states phase it in over the following year | 85 % | 23.3 billion euro-equivalent |
| − | Care that reappears as unpaid hospital bills Setting, range 5 to 35 percent: each person left uninsured when Tennessee cut Medicaid added close to 900 dollars a year of unpaid hospital care, and hospitals in expansion states are projected to write off 7.0 to 8.0 billion dollars more in 2027 for 5.1 to 5.8 million newly uninsured; that care goes on and is paid by hospitals, other payers and public write-off funds, so it is not a saving [11][13] | 4.0 million people × about 1,400 dollars = 4.7 billion euro-equivalent, about a fifth | 18.6 billion euro-equivalent |
| × | Weight of a dollar in the federal budget the standard weight for public money on this site, against 2.5 on the receiving side | 1.0 | 18.6 billion euro-equivalent |

Plausibility
That fewer people on Medicaid means less Medicaid spending is arithmetic, not a prediction. What has to be shown is that people do in fact leave, and here there is more than a model. Arkansas ran the requirement for nine months in 2018: more than 18,000 adults lost coverage, and the study that measured it compared 30-to-49-year-olds, who were subject to the rule, against younger and older adults in the same state and against adults in Kentucky, Louisiana and Texas [3]. The confounder that would otherwise dominate — that Arkansas was on a different economic path — is what the three comparison states are there to absorb, and the age comparison inside the state absorbs the rest. Reverse causation does not arise, because the rule was imposed by the state and not chosen by the people it removed. Georgia's programme and New Hampshire's short-lived one point the same way [5]. What is estimated rather than observed is the size at national scale, and that doubt is carried by the range around each step rather than here. The Plausibility is high for a budget saving: the disenrolment it rests on has been observed under a comparison design, and only the national scale is projected.
